A compact slotted patch antenna for ultrawideband application

A compact antenna with ultra wideband characteristics is proposed which covers the dimension of 23 × 21 mm
²
. It has a rectangular slotted patch with a circular slot, microstrip feed line and a tapered slot ground with a thickness of 1.6 mm which covers the inexpensive FR4 dielectric substrate. The proposed antenna covers a wider bandwidth of 10.1 GHz (2.90-12 GHz) with stable radiation pattern and constant gain which is ideal for UWB applications. The simulation is done with CST and HFSS simulator. The proposed antenna is low cost, compact in size and have good specifications which make it suitable for using UWB applications.
